Subject: perf bench unexpected behaviour

Hi all,
If I run
	perf bench --format=simple all > test.out

I get this line repeated hundreds of times in test.out

	# Running sched/messaging benchmark...

interleaved with the useful output.
It's only printed once if I call it from the command line, it just
redirecting to a file that does odd things. 

AFAICT the message is only printed once, so any ideas why it does this? 
and is there anything I can do to stop it?

This is on 3.6-rc*, I haven't tried any earlier kernels.

thanks
Richard
